My ejb is

import javax.ejb.*;

import org.jboss.annotation.ejb.LocalBinding;
import org.jboss.annotation.ejb.RemoteBinding;

@Stateless
@Local ({CalculatorLocal.class})
@LocalBinding (jndiBinding="EJB3Trail/LocalCalculator")
@Remote ({Calculator.class})
@RemoteBinding (jndiBinding="EJB3Trail/RemoteCalculator")
public class CalculatorBean implements Calculator, CalculatorLocal {


public String foo(String param){
return "hola"+param;
}
}

My interface ejb local is


import javax.ejb.Local;

@Local
public interface CalculatorLocal {

String foo(String param);
}

My Servlet invoque ejb 3.0 is

import java.io.IOException;
import java.io.PrintWriter;

import javax.naming.InitialContext;

import javax.servlet.*;
import javax.servlet.http.*;

import model.CalculatorLocal;

public class ControlServlet extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=windows-1252";

public void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {response.setContentType(CONTENT_TYPE);
CalculatorLocal cal = null;
try {
InitialContext ctx = new InitialContext();
cal = (CalculatorLocal) ctx.lookup("EJB3Trail/LocalCalculator");
} catch (Exception e) {
e.printStackTrace ();
}

//Problem al invoque method
String msj = cal.foo("fred"); //The problem is here


PrintWriter out = response.getWriter();
out.println("");
out.println("ControlServlet");
out.println("");
out.println(""+msj+"");
out.println("");
out.close();
}
}

Are you sure the ejb jar that you have deployed is the correct version and contains this method? Also, is there any other jar containing this ejb (but not the method) in the classpath which might be causing this issue?

[fduartej1]

Yes. I am sure good deploy ejb jar,

My problem is solutions.

I deploy ear in server all, and not report error in this server
